INTRODUCTION A prior objective is to improve the sustainable energy development by implementing strategic technology over exhaustible fossil based fuel replaced by renewable energy resources. Among them nowadays photovoltaic energy has an increased importance in all over electrical power applications, since it is considered as an abundantly available renewable energy resource and it is inexhaustible in nature [1]. The photovoltaic processes are completely solid state and self contained. It has no moving parts and has no materials consumed or emitted [2]. Additionally, they generate power near the load centers, which eliminates the need to run high-voltage transmission lines through urban and rural areas [3]. Due to the erratic nature of solar energy, stand-alone PV system usually needs other generation sources or energy storage devices to form a hybrid systemThe storage device can be superconducting magnetic energy storage (SMES), battery bank, FC electrolyzer system or a super capacitor bank [4-12]. An important characteristic of solar panels is that the available maximum power is provided only in a single operating point given by a localized voltage and current known, called Maximum Power Point (MPP). Another problem is that the position of this point is not fixed but it moves according to the irradiance, the temperature and load. Because of the relatively expensive cost of this kind of energy we must extract the maximum of watts of solar panels. This requires a mechanism for the pursuit (tracking) of the MPP called maximum power point tracking (MPPT) so that maximum power is generated permanently. Artificial intelligent technology may be added to improve the maximum power tracking capability of solar panel [13-14].
